Abstract:
Nano fertilizers and micronutrients are among the products that are massively presented in the Agriculture and Packaging section of the Fourth Nanotechnology Festival and Exhibition in Tehran.

Nano fertilizers play an important role in increasing the quantity of agricultural products and in removing the environmental hazards.

In this year's exhibition, Sepehr Parmis, Markazi Nano Pazhoohesh, Gilan Zak, and Sodoor Ahrar Sharq companies have presented various products in the field of nano fertilizers.

One group of the different products presented in Agriculture and Packaging Zone of the Exhibition is the third generation of nano fertilizers. The purity of elements is very high in such fertilizers. One of the advantages of such fertilizers is that they can be used in tiny amounts, to the extent that an adult tree requires only 40-50 kg of fertilizer while an amount of 150 kg would be required for ordinary fertilizers.

Fertilizers presented by the companies in this zone are used particularly for rice, apple, maize, and citrus. Dispersing nutrients to all parts of the plant in a homogenous manner increases the quantity of the product. Micronutrients also yield the highest possible results in the production quantity and quality of the agricultural products.

Soil poverty, limy circumstances, and salinity of waters may risk the society's health and nutritive security. Therefore, the use of new methods and fertilizers can be an important role in the progress and health of the agriculture section.
